2 Day e book to success in CAT

I just came across a site with above lines. Don't know how it is possible though the writer claims to be a passout of IIMA and also has a GMAT score of 780 wow?? There are so many books in marked which can get you an IIM call without much hard work (as wriiten in all the books with different words)but I think this must be the first e book.. some thing like "Be a millionaire in 2 days" and that's also w/o going to KBC :-)) Be sure that you don't have any other way of wasting your money before going for such stupid stuffs which promises a lot and delivers NOT.
